Résumé
Everything is changing rapidly, and the development of technology and information has changed significantly in the last few decades. Education, like other aspects of society, needs to change and adapt appropriately. Online teaching and learning is a new approach for the authors to use information technology via distance learning programs, especially in the way relationships and interactions altered between students and teachers or instructors when the Coronavirus disease (Covid-19) pandemic occurred. Mahidol University responded to the situation rapidly and announced that academics could use students' online teaching free of charge. The research aim is to identify the advantages and disadvantages encountered while applying the online method of instruction. Implementation, the online program has made teaching possible, but it has disadvantages that may decrease the quality of education. Nevertheless, it replaced traditional teaching methods by utilizing the web-based program, Webex Meetings, across the whole university. Conclusion, this new approach has changed and opened horizons earlier than the authors thought and far beyond our beliefs concerning traditional education methods for future generations. © 2022 Chayaporn Saranpuetti, Piyatida Khajornchaikul, Vallerut Pobkeeree.
